SPECIFICATION forming part of Letters Patent No. 366,146, dated July 5, 1887.

Application filed May 17, i886. Serial No. 202,353.

To @ZZ whom it may concern:

Be itknown that I, `Aiifeusr BREHMER, ot" Leipsic, Germany, have invented a new and Improved Paper-Box Machine, of which the following specification is a full, clear, and eX- act description.

This invention relates to a machine for makingl and cutting off clasps from wire and uniting the corners of pasteboard paper boxes with such clasps.

The invention consists in the various elements ot' improvement hereinafter more fully described.

In the accompanying drawings, Figure I represents a side View of the machine. Fig. II is an end -view of the same. The other thirteen igures represent several parts in detail, and show the saine in various positions of the operation. j

Similar letters represent similar parts in all the Iignres.

A is the frame of the machine, the top surface of the projecting forward end, D, forming an angle of ninety degrees to receive two sides of the box to be united. On a bolt, E, fast in the frame thelever l turns, operated either by hand, foot', or power.

B is a lever turning on pin 3,attached to the.

frame A. On the forward head, C, of this lever all parts are supported and guided necessary for forming, bending, and driving the clasps around the corners and into the sides of the boxes. The various parts receive their motion from segments 4. and 5, turning on bolts 6 6, on the sides of the head C of lever B, and connected through rod 2 with the upper end of the lever l. These segments 4 and 5 are connected together at their upper ends by bolts s s, and are .provided with cam-shaped grooves to operate the various parts, as hereinafter more fully described. The lower end of the lever B is provided with a roller, 39, working in a cam-shaped groove, 40, made in the lever 1, to communicate motion to said lever B. The pasteboard pieces to form the box are placed upon the angular top surface, D,of the frame A, the edge of one piece abutting against the adjoining piece, as shown in Figs. III and IV. The lever lis then moved in the direction of arrow 50, whereby the action of the cam-shaped groove 4.-() upon roller 39 causes the lever B to move downward and to (No model.)

through rod 10,.the lever l1, whereby the.

pawl 12 acts upon the ratchet-wheel 13 and turns the same. This ratchet-wheel 13 is attached to one of a pair of rollers, 14 between which the wire 15, from which the clasps are made, is held, and by their motion move the Wire through the channel 16 into a channel, 16X, in the block 17, attached at the lower end of head C and between the shapingblock 25.

In Fig. XI the position of the wire 15 in the block 17 at the beginning of this operation is represented, and Fig. XII shows the position of wire 15 in the block 17 at the end of this operation. After the completion of' this op eration the camgroove 1S in segment 5 acts upon the roller 19, attached to the slide 20, guided in the head O, Figs. I, VI, and IX. To this slide 20 the rods 2l 21 are attached, these rods being connected to cranks 22 22, fast on the ends of spindles 23, turning in the block 17. `The ends of these spindles 23 23 have triangular projections d. By the turning of these spindles one of the projections d will, in connection with a knife-block,c, placed' in the block 17, cut the wire 15, after which these projections d d, coming in contact with the ends of the cutoff piece of wire, will bend these ends over the shapingblock 25, situated in the block 17, Figs. XI, XII, and XIII. The ends of the piece of wire (which is to form the clasp) are bent so as to form with the central part angles of about sixty degrees. By changing the dimensions of the cranks 22, or the amount of motion of the slide 20, any desired angle may be obtained.

Fig. XIII shows th'eposition of the several parts when this operation of bending the clasp has been completed. When this operation is completed, the action of the ca1n-groove 1S turns the crank 22 so far back as to allowa free passage of the claspfastener 26 between these projections d d. (See Fig. XIV.) The camgroove 27 in the segment 5 acts now upon the roller 28, attached to a slide, 29, moving said slide downward. At the lower end of the slide 29 the clasp-fastener 26 is attached by means of a bolt having a round head, 30. At the beginning of this downward motion of the slide 29 this head 30 comes in contact with an inclined surface, 31, of the rod 25, the upper end of which is loosely connected to the head C, in order that it may be bent outward, and the lower end of which forms the shaping-block for the cut-off wire, as before described. By the action of this head 30 against theinclined surface 31 this lever 25 is bent outward sufficient to bring the lower end or shaping-block of said lever lclear of the block 17, and thus allow the clasp-fastener 26 to pass freely downward. rlhe bottom of the fastener 26 is cutout to form an angle of ninety degrees. The further motion ofthe fastener 26 moves the pre-v viously-formed clasp upon the edge of the` pasteboard pieces, which form parts of the box,and bends the previously straight central part of the clasp over the edge, at the same Atime forcing the ends through these side project some distance on the inside.

pieces.r The forcing of the ends of the clasp through the sides forming the box without any extra external guide is only possible when the ends of the clasp are bent at or about an angle of sixty degrees with the central part of the clasp.

Fig. XIV represents the parts after this operation is completed. The ends of the clasp, after having been passed through the sides, (See Fig. XIV.) The operation of bending these projecting ends to lie fiat against the inner` surface, and at the same time secure the clasp, is performed as follows: Near the end of the motion of the lever 1 a projection, 32, on said lever comes in contact with the end of a rod, 33, situated in the top end, D, of the frame A, moving the same outward. The forward end of this lever 33 is connected with a bellcrank lever, 34, which operates a plate, 35,

so as to move the same upward. (See Figs. I,

of the box. To press these burrs or uneven parts of the box smooth again, part of the inclined surface at 43 is made flat, so that while passing over these rough parts the same will be pressed smooth. A small cavity, 42, is made in these surfaces for the turned-over part of the clasp. When the above-described operations are completed, a spring, 36, attached to the lever 1, moves the same, as well as all parts connected thereto, back again into their original position, and the spring 37, attached to the frame Aand to thelever 33, (see Fig. 1,) moves the rod 33 inward again, and consequently the plate 35, in the position as shown in Fig. XIV. At the saine time the head 30 has moved above the incline 31 on lever 25, when a spring, 38, forces the lower end or shapingblock of said lever into its original position, ready for the nextopcratiou.

I claim as my invention* 1. The combination of lever 1 and segment 4, providedwith cam-groove 7, with slide 9, rod 10, lever l1, pawl 12, ratchet-wheel 13, and rollers 14, and the headvG, arranged to opcrate in the manner and for the purpose sub-l stantially as described.

2. The combination of lever 1 and segmentl 5, provided with camgroove 18, with slide 20, rods 21, cranks 22, and spindles 23, having triangular ends d, and with shaping-block 25, substantially as specified.

3. The combination of lever 1 and segment 5, provided with cam-groove 27, with slide 29, and clasp-fastener 26,substantially as specified.

4. The clasp fastener 26 in combination with slide 35, provided with top surfaces inclined at an angle of ninety degrees. to each other, the teeth 4l at the top, and the smooth surfaces 43 at the bottom of saidsurfaces, substantially as and for the purpose described.

5. In a paper-box machine, the combination of the segments 4 and 5, provided with camgrooves 7, 18, and 27, and turning on centers in the head C, rod 2, and lever 1, with slides 9, 20, and 29, substantially as described.

In ltestimony whereof Ihave signed my name to this specification in theprcsenceof two subscribing witnesses.
